TRANBIORMER RADIATOR.

Application filed April 29, 1922, Serial No. 557,325. Renewed. January 24, 1927.

My invention relates to radiators, and it has particular relation to radiator elements for transformers of the oil-insulated selfcooled type.

One of the objects of my invention is to provide a transformer radiator in which the various units thereof are constructed of pressed metal and welded together to form a unitar structure whic ma be quickly and easi y attached to a t ans ormer tank.

Another object of my invention is to ro vide a radiator, of the character descri ed, in which the various parts are rovided with flanged portions which are so isposed as to be easily accessible for welding.

A further object of my invention is to provide a radiator, of the character designated, which embodies a connection adapted to secure a radiator to a tank and which establishes a communication therebetween which may be constructed from a plurality of" complementary pressed-metal members welded together whereb a desired number of radiator units may be mounted upon a transformer tank and occupy a minimum amount of floor space.

In the accompanying drawings, Fig. 1 is a view in side elevation, of a radiator constructed in accordancewith my invention.

Fig. 2 is an enlarged plan view of the structure illustrated in Fig. 1.

Fig. 3 is a front elevational View of the upper portion of the radiator illustrated in Fig. 2.

Fig. 4 is a side elevational view of the structure illustrated in Fig. 3.

Fig. 5 is an enlarged side elevational view of the member which supports the radiator upon a transformer tank and which establishes communication therebetween.

Fi 6 is a horizontal sectional view on line I--VI of Fig. 5, of one of the side portions of the connecting member.

Fig. 7 is a transverse sectional view taken on line VIIVII of Fig. 5.

Referring to the drawings, a radiator constructed in accordance with my invention is shown as comprising a plurality of relatively flat envelopes or units, indicated as a whole by the numeral 1, which are disposed in spaced and parallel relation with respect to each other and connected together at their upper and lower extremities for fluid commun cation therebetween by means of header portions 2. The units 1 are preferabl arranged in two groups with upper and ower hea er portions 2 of the innermost unit of each group connected to common communieating and supporting members 3 on each side thereof, which are in turn mounted upon the side wall of a transformer tank 4, and which establish communication between the interior of the tank and the radiator.

Each of the units 1 consists of two complementary side members 5 and 6, respectivcly, of substantially dish shape, provided with outwardly extending peripheral flanges 7 adapted to be welded together to form a seamless oil-ti ht structure. The two side members 5 an 6 are further rovided with a plurality of vertically-exten ing stiffening ribs or corrugations 8 which extend substantially the entire length of the members and which are welded together at intervals, as indicated at 9.

The header portions 2 of the units 1 are formed by continuations of the side members 5 and 6 which are bent to form extruded portionslO and 11, respectively, and which cooperate with each other, when the two side members are welded together, to form a substantially cylindrical chamber communicating with the interior of the unit. The portion 10 of each of the headers 2 is provided with an outwardly extendin flange 12, and the portion 11 thereof is ormed with an inwardly curled edge or flange 13. When the various units of the radiator are arranged in position and welded together, the flanges 12 of the portions 10 of each header extend into the portions 11 of the adjacent header member and into engagement with the inwardly extending flange 13 thereof. The flanges 12 and 13 are then welded together along their edges, as indicated at 14.

The headers 2 of the outermost units of the radiator are closed by cap members 15 which are provided with inwardly extending annular flanges 16 which are adapted to be welded to the flanges 13 of the headers 2.

The connecting members 3 comprise two indicated at 19.

complementary portions 17, each of which is provided wit an outwardly extendi flange 18, which are adapted to be welde together along their outer edges, as indicated at 19, to form a unitary structure. Each of the portions 17 is provided with an aperture 20 the e#: of which is bent inwardly, as at 21. en the parts are assembled, the outwardly extending flanges 12 of the header portions 2 of the innermost units 1 roject into the apertures 20 and are welded to the flanges 21 of the member 3.

From an ins tion of Figs. (Sand 7 of the drawings, it will be observed that the th forward or outer portion of each of the members 3 is relatlvel flat and the sides thereof are so inclined that the cross-sectional area of their rear or inner portion is substantially circular and projects into a suitable connection 22 which is adapted to be detachabl secured to the main tank by means of bo ts 23.

In assemblin the radiator constructed as above described, the various portions are built u commencing with the outermost units 0 each of the grou disposed on opposite sides of the mem r 3. That is to say, the cap portions 15 are welded in position to close the apertures in the side por tions 5 of the outermost units and the aide portions 6 are then welded in position on the member 5 by means of the peripheral flanges 7. The side rtions 5 of the adjacent unit are then we ded in position on the side portion 6 by means of the telescoping flanges 12 and 13, and a side portion 6, in turn, is welded on the side member 5. The operation is then repeated until a desired number of units have been welded together. The portions 17 of the members 3 are then separately welded to the innermost of the units 1 of each of the groups by means of the telescoping flanges 12 and 21. The two grou are then secured together by weldlng t e portions 17 of the member 3 together along t eouter edge of the flanges 18, as

The inner portion of the member 3 may be tapered slightly, as indicated at 25, and is adapted to be forced into a correspondingly tapered aperture 26 in the connecting member 22 and welded thereto, as at 27,

From the to it will be ap arent that, by means 0 the above-descri construction, ave strong, compact and relatively light radiator is provided that is prac tically an integral structure and is of neat appearance by reason of the fact that a large proportion of the welded seams aredisposed wit in the radiator.

I claim as my invention:

1. A radiator comprising a plurality of groups of communicating radiating units, and a member disposed between sai groups and communicating therewith for establish ing communication with a tank.

2. A radiator comprising a plurality of groups of communicatlng radiating units and a two-part member disposed between said gnou and in communication therewith for estab ishin communication with a tank.
